Circumference is 40 in and area is 150 in²
Step-by-step explanation:
- Step 1: Find the circumference of the circle when radius = 7 in
Circumference = 2πr = 2 × 22/7 × 7 = 44 in ≈ 40 in
- Step 2: Find the area of the circle.
Area = πr² = 22/7 × 7² = 154 in² ≈ 150 in²
Answer:
800 km
Step-by-step explanation:
Does the plane have a speed of it's own? I don't see it, so will assume the plane is simply travelling at 300 km/h.
(300 km/hr)*(1 hr/60 min) = 5 km/min
(5 km/min)*(160 min) = 800 km in 160 minutes
